BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 461,936, dated October27, 1891.

Serial No. 383,764- (No model.)

To 011% whom it may concern.-

Be it known that I, ENOOH J. FARGO, acitizen of the United States,residing at Lake Mills, in the county of'Jefferson and State ofWisconsin, have invented a new and useful ButterWVorker, of which thefollowing is a specification.

This invention relates to butter-workers; and the object of the same isto provide a device of this character possessing a new movement in thisclass of machines.

To this end the invention consists of the details of constructionhereinafter more fully described and claimed, and as illustrated in thetwo sheets of drawings, wherein- Figure 1 is a general perspective Viewof this machine. Fig. 2 is another perspective view looking from adifferent point. Fig. 3 is a plan View of Fig. 2, omitting the rollersand table. Fig. 4 is a section on the line 4 4: of Fig. 3. Fig. 5 is anenlarged perspec tive detail of the bracket at the inner end of one ofthe rollers. Fig. 6 is a central longitudinal section of the entiremachine. Fig. 7 is an enlarged section through the upper end of thecross, the collar, and the rod. Fig. Sis an enlarged section through theouter end of one of the horizontal arms of the cross and a plan of theuniversal joint. Fig. 9 is a detail of the cross and the crank operatingin the slot. 1

Referring to the said drawings, the letter F designates a suitableframe-work carrying friction-rollers F'and having a central pivotpin C,upon which is journaled a slightly concaved or dished table or disk .D.On the lower face of this disk is a track 15 having a toothed ring T,and the former moves over the friction-rollers F while the latterengages a gear-wheel G, mounted upon the main shaft M, which has fastand loose pulleys, as shown, and is adapted to be driven from a suitablesource of power in a well-understood manner forming no part of thepresent invention. Two of the bars of the frame-work F rise above thedisk or table D, as shown at f, and are connected at their upper ends bya horizontal bar H, and pivoted at g in this bar is an X-shaped casing,which I will call the cross X. The lower end of the vertical member ofthis cross is provided with an elon gated slot E, that engages a crank min the shaft, as seen in dotted lines in Fig. 4. The

outer ends of the horizontal armsare provided with hearings or eyes I,and the upper end of the vertical arm is grooved or notched, as at N,Fig. 7, a collar A surrounding this upper end and having a set-screw Stherethrough.

In Fig. 5 is shown a bracket K, whose outer ends have eyes I and whoseupper end has a notch N and a collar A, the same as the cross, and whosebody is pivotally connected by a horizontal screw h with a block Qloosely mounted upon the center pin 0.

The letter L designates a rod which connects the upper ends of the crossand the bracket. The ends of this rod are bent downwardly, as shown, andare seated in the notches N in the upper ends of the cross and thebracket, the collar A surrounding these ends, and the set-screws Sholdingtheparts in position. The upper end of the shaft of each rollerconnects bya universal joint 0,, with a stub-shaft Z, journaled in eacheye I at the ends of the cross X. These shafts Z carry gears G on theirother ends, which are in constant mesh with a geariG', journaled on thepivot g of the cross, but outside the bar H. Below the gear G is anidle-gear G which communicates motion from a gear G on the shaft M tothe gears G, and thence to the two rollers, no matter at what positionthe latter stand.

R R are rollers, preferably conical and with longitudinal groovesseparated by ribs 7', and through each roller extends a shaft whoselower end has a rounded head I), which is journaled in the eye I of thebracket. Power being applied to the main shaft the gearwheel G causesthe table D to rotate. At the same time the crank m causes the cross Xtooscillate about its pivot g in the bar H, and a simultaneousoscillation is imparted by the rod L to the bracket K. One of therollers R, standing at each side of the rod L, and being connected atits ends with the bracket and the cross. As these latter are rocked, theroller rises and falls oppositely to the other roller. By adjusting thescrews h the block Q can be moved vertically upon the center pin 0, andthe inner ends of the rollers are thus raised or lowered, the dependingends of the rod L being suitably adjusted, as may .be required. Thebutter to be worked is placed upon the table D and passes first underone roller and then under the other, the rollers turning by the gearingfrom the shaft, as will be understood. I The dishing shape of the tablecauses the buttermilk to run to the center thereof and pass downwardlythrough the hole around the center pin 0, and a suitable trough Y,leading therefrom, conducts it to a receptacle. The ball-and-socketjoints at the inner ends of the rollers permit the latter to turn and tomove slightly out and in when the bracket is raised or lowered, and thisrising and lowering is to adapt the machine to do more or less work, aswill be well understood by a person familiar with the Working of butter.The universal joints at the outer ends of the rollers keep themconstantly connected to and rotated by their driving-gears, and thelatter are of course in perfect mesh at all times with the central gearG.

WVhat is claimed as new is- 1. In abutter-worker, the combination, witha dished circular rotating table, of a pair of conical rollers above thesame and means for raising and lowering them alternately andintermittently, substantially as described.

2. In a butter-worker, the combination, with a frame-work, a main shafttherein having a gear and a crank, and a rotating disk or table mountedon a central pin in said frame- Nvork and having a toothed rack engagingsaid gear, of extensions from the frame-work connected by a horizontalbar, a cross pivoted to said bar and oscillated by said crank, a bracketpivotally connected to said pin, and rollers journaled in said bracketand in the horizontal arms of said cross, substantially as described.

3. In a buttenworker, the combination, with a frame-work, a central pinrising therefrom, a rotating disk or table mounted on said pin, ahorizontal bar connected to said fram ework, a cross pivoted to saidbar, and means for oscillating the cross, of a block adjustably mountedupon said pin, a bracket pivoted to said block, a rod connecting saidcross and bracket, the latter member having eyes in its outer ends, androllers connected by ball-and-socket joints with said eyes, and byuniversal joints with the cross, substantially as described.
